If I read the FAQ correctly, it doesn't do exactly the same thing as a Tremsetter. Sounds like you can have it full floating (off), locked (on), or blocked for dive-only.
The Tremsetter stabilizes the bridge while retaining full floating tremolo function. In my experience, it greatly improves the tone and sustain of a Floyd-equipped guitar, and it actually makes bending (and finger vibrato) easier, since the trem doesn't sag forward when you bend strings (or palm mute or rest your hand on the bridge). A regular Floyd (or any floating trem) might give you the illusion of easier bending, but you actually have to bend farther to achieve the same note, again due to the sag effect. You are also losing string energy when the bridge sags - this (besides the lack of string-to-body coupling) is what causes the decrease in tone and sustain.
(In case you were wondering, there's no difference in string tension between different bridge types - tension is purely a function of string gauge and tuning pitch.)
Nothing wrong with the Tremol-no, they're just different animals.
